4392-55-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4392-55-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4392-55:
(6*4)+(5*3)+(4*9)+(3*2)+(2*5)+(1*5)=96
96 % 10 = 6
So 4392-55-6 is a valid CAS Registry Number.

Electrochemical Behavior of Azoxybenzene-4,4'-disulfonamide at Pyrolytic Graphite Electrode

Goyal, R. N.,Bhargava, Sandhya

, p. 2662 - 2667 (2007/10/02)

The electrochemical reduction of azoxybenzene-4,4'-disulfonamide has been studied in the Britton Robinson buffers of pH range 3.0-0.6 at a pyrolytic graphite electrode.The electroreduction was found to occur in a single well defined 4e, 4H+ peak.The hydrazo compound has been identified as the main product of the elctrode reaction.
